Abstract
The invention provides a kind of packaged type curing system that can carry out cure process to the side surface of rail's end portion on the railway curve track in the operation, this device utilizes train off time or blocking time to drive to the curve side grinding place, while travelling side surface of rail's end portion is carried out cure process, Rockwell hardness reaches (HRC＞53 °).Thereby effectively solve sharp radius curve rail side and seriously wear away problem, this device can be at any time road up and down, form by traveling generator car and waterwheel and rail hardening dolly.This apparatus features is to make simplely, can prolong application life of rail greatly, and what can guarantee in the utilization to drive a vehicle is perfectly safe.
Description
The present invention relates to a kind ofly can carry out the packaged type device of cure process to the side surface of rail's end portion on the railroad track in the operation.Also can carry out cure process to side surface of rail's end portion and other steel parts with the form of fixed point.
The upward strand rail of railway curve, particularly sharp radius curve, undesired side wear (abbreviation side grinding) all takes place in major part, side grinding transfinites and has shortened rail application life, cause the heavy workload that switches tracks simultaneously, upset normal transport order, increased cost of transportation.How to reduce or the undesired abrasion of curve of extinction side surface of rail's end portion are railway interests's important topics.All launch a massive attack on him for many years, up to the present, the way of taking has following several: adjust the hypervelocity of rail cant, adjustment curve, and be coated with the wet goods method to the head side of rail.These methods can both alleviate the abrasion of rail side to a certain extent, but the undesired side consumption that can not effectively solve the generation of wheel-rail contact relationship and various factors is wasted, and particularly can not effectively solve large automobile and diesel locomotive, import locomotive to side surface of rail's end portion abrasion on the sharp radius curve.
Want effectively to solve curved steel rail head side wear, for people's way in common knowledge is that the hardness that improves side surface of rail's end portion strengthens its scuff resistance.How can improve the hardness of side surface of rail's end portion? to this problem, China railways department does not still relate to, and does not do trial yet.Can once be there there such imagination: in rail manufactory, be hardened in the rail side? according to the activities that rail is made, can carry out quench hardening to whole one steel rail and handle.Fragility is big after the whole one steel rail quench hardening, greatly reduces elasticity, is difficult to crooked rail when railway curve is laid a railway track.Given this plant situation, rail manufactory carries out comparatively complexity of hardening process to side surface of rail's end portion, so manufactory only handles carrying out quench hardening in the 200 millimeters scopes in rail two ends now, to solve the needs of rail joint pounding wear; Also once attempt in the railway certain limit, to set up the rail surface quenching and hardening device of fixed point form, but caused the drawback of round transport rail deficiency in economic performance.Owing to these reasons, the problem of side surface of rail's end portion sclerosis is not still carried out on the railway curve.
Purpose of the present invention is to provide a kind of can also can carry out cure process packaged type curing system to its head side to being taped against the rail on the railway curve.This device can carry out cure process while travelling to side surface of rail's end portion in orbit.
The present invention realizes with the following methods: equip one can be voluntarily the railroad track traveling generator car and a dress waterwheel in road up and down, and rail hardening dolly.Generating is walked between driving and the rail hardening dolly and is linked with 200 meters long cables, links with 200 meters Great Wall Software's water pipes between waterwheel and the rail dolly, forms packaged type rail hardening device thus.Design has the storehouse hole of rail hardening dolly on waterwheel.When this device is not worked, just the rail hardening dolly is loaded in the storehouse hole, when carrying out curing, it is positioned on the track from the waterwheel taking-up.
The course of work of this device is as follows: utilize train off time or construction and blockade time, these device traveling generator car are drawing the waterwheel that the sclerosis dolly is housed, drive to interval curve place, and immediately the rail hardening dolly is positioned on the track, while traveling generator car and waterwheel rely on automatic up and down track device to transfer to the track outside and lay, to the power supply of rail hardening dolly, water supply, the rail hardening dolly hardens to side surface of rail's end portion while travelling by certain speed in orbit respectively for traveling generator car and waterwheel.But the everywhere hardening rail is extended for 400 meters.If utilize blockade or the little circuit of rate of traffic flow of long period, generating is walked driving and waterwheel and can not descended the road directly to draw the rail hardening dolly to carry out work.
This device to the basic principle that rail hardens is: the traveling generator car send decides frequency high-tension current input rail hardening dolly transformer, transformer by dolly becomes low-pressure high-strength degree electric current, forming eddy current near the V-arrangement induction coil of side surface of rail's end portion produces high temperature and makes the local rail level of rail heat up (general 3-5 in second temperature can reach 800 ℃) rapidly at interval 2-3 after second, use sparge pipe or airduct to high temperature face injected cool aqueous medium, or air dielectric, form heat treatment process.Control rail level temperature is reduced to 200 ℃, utilizes waste heat to carry out tempering again.Rail level Rockwell hardness (HRC＞53) through processing really up to the mark.For being perfectly safe of guaranteeing to drive a vehicle,, being designed to 60 kilograms and being convenient to two people and moving the weight of sclerosis dolly.The following road time of design is 20 seconds.The invention will be further described below in conjunction with accompanying drawing:
